Caitilin Espinosa, a spokeswoman for the Fort Bend County Sheriff's Office, toldPeople Magazine on Sunday that Christy Sheats allegedly had a history of mental illness.

The sheriff's office had been called to the family's home before "for previous altercations" regarding a "mental crisis," Espinosa told the magazine.

The sheriff's office would not elaborate on those statements Monday, but did say authorities had been called to the house 14 times since January 2012.

"Some were alarm issues, but due to legal constraints issued by the county attorney, the Fort Bend County Sheriff’s Office cannot describe the other calls for service, or release the 911 calls at this time," the sheriff's office said.

On her Facebook profile, Christy Sheats routinely praised her daughters.

"Happy Daughter's Day to my two amazing, sweet, kind, beautiful, intelligent girls," she wrote in September last year. "I love and treasure you both more than you could ever possibly know."

She also posted messages in support of the Second Amendment.

"It would be horribly tragic if my ability to protect myself or my family were to be taken away," she wrote in March, "but that's exactly what Democrats are determined to do by banning semi-automatic handguns."
